the graph provides the information about the changes of British women’s birth rate in six specific age groups between 1973 and 2008. Overall, there was a swap between women in their latter thirties and under 20 years.

In the declining groups, there were 140 women who aged from 25 to 29 gave birth in 1973, fluctuating to about 120 and remained stable for the rest of the surveyed period. Meanwhile, women from 25 to 29 years and under 20 years shared the similarity, specifically, both started at about 122 and 60 respectively, decresing steadily to around 117 and 40 in the last year. In addition, women who were over 40 gave only 20 births in 1973 before dropping slightly to half in 2008.
